recensies: These were close to what I expected but not quite. Appeared to be well made but I've only had them installed in my RV for a day so can't comment on durability yet. Fit was almost exactly what I needed for the RV sockets I was working with. The round disk was just the right size for the lamps reflector which I had previously measured. I did have to trim off the pins on one in order to get the LED to seat properly but that was minor. Other than that, installation was a breeze.rnrnWhat I don't like is that the light is just slighly bluer than what I was seeking. This is probably more evident in my case since I am comparing the new LED's to some still existing halogen bulbs. My biggest issue is that these are not quite as bright as I would have liked. They are not as bright as the 10 watt halogens I am trying to replace. If I order more, I will be looking for something in the 3 to 3.5 watt category. But these complaints are relative to my situation and yours may be different.
